BufferedImage to InputStream

Use the ImageIO class

> I would now like to take a BufferedImage which is dynamically generated and feed it to the InputStream.  

That does not seem to make sense, what exactly is it you are trying to achieve?

following shows you how to save a BI to a file if thats what you nned:

Looking at the ImageIO JavaDoc, I can see where I can read a InputStream and return a BufferedImage.  I already have a BufferedImage and need to return a InputStream is my problem.  Am I overlooking what you intend?

BTW, how on earth do you get to the posts so quickly??????

Thanks,

What do want the input stream for?

I'm actually sending the data over a socket......a formatted response to a web request specifically.  The image itself is generated dynamically and not read from a file which is why I'm trying to figure out how to turn the BufferedImage directly into a InputStream.

I still don't see what you need an InputStream.
If you want to write it to somewhere then use ImageIO.write() with the output stream you want to write it to

I'll try posting the relevent code:

//generating screenshot
BufferedImage bufferedImage = robot.createScreenCapture(area);

//grabbing output
PrintStream out=new PrintStream(new BufferedOutputStream(socket.getOutputStream()));

//setting mime type
String mimeType="image/jpeg";
       
//returning ok message and mime type to browser
out.print("HTTP/1.0 200 OK\r\n" + "Content-type: "+mimeType+"\r\n\r\n");

//send data to client
//***********IF I'M SENDING DATA FROM A FILE, I USE THE FOLLOWING CODE
byte[] a=new byte[4096];
int n;
while ((n=f.read(a))>0)
     out.write(a, 0, n);
out.close();
//************END SENDING


The last section is what I need to change.  I would like to send the BufferedImage I created at the beginning of that snippet

Thanks,
David

use the line I posted above, but you need to write the image to the sockets output stream and *not* the PrintWriter (thats for text data)

Whoa, whoa, whoa.  You're right....I didn't see the logic in it at first and I'm glad you didn't just spell it out completely cause it made me investigate a little bit more.

Lost my connection before I could get back to post this.

Thanks,
